Por una parte, los resultados más relevantes indican que el comportamiento sexual posee un efecto de tipo ansiolítico o atenuante del estrés, que se manifiesta tanto en la conducta de los sujetos como a niveles fisiológicos o neuroendocrinos. Por otra parte, hay estudios que hacen referencia a la relación de signo contrario, es decir, cómo el estrés afecta el comportamiento sexual de los animales.

The main research on memory began in the 70s and the most important conclusions have been derived, on the one hand, from animal experiments, and on the other hand, from clinical studies of amnesic patients. Many classification systems of memory have been proposed. First, authors have distinguished among the different phases involved in the process of memory formation: short-term and long-term memory. Second, declarative and non-declarative memories have been recognized. Last, researchers have conceived the need to evaluate memory in a systematic manner through behavioral as well as pharmacological means, in different moments or times to be able to have independent access to the study of the different memory phases or types of memory. This approach to the study of memory has allowed evaluating drug effects on memory and also understanding the molecular mechanisms involved in memory processes. In addition, this research has also aimed at studying brain regions implicated in the diverse memory phenomena under investigation.

The exposure to novel situations (e.g. exploration of a novel open field) has been used widely to modulate (i.e. either enhance or deteriorate) learning and memory. The aim of the present study was to test whether open-field exposure could modulate consummatory extinction. The results indicated that open-field exposure accelerated the extinction response (i.e. experimental animals provided novelty exposure had lower consummatory behavior than control animals) when applied beforebut not afterthe first extinction trial, or when applied before the second extinction trial. The results suggest that environmental treatments such as novelty exposure provide a valuable, nonpharmacological alternative to potentially modulate extinction processes.

However, the specific and differential effects of musical activities are a new focus of research. Therefore, this study aimed to investigate the effect of musical improvisation, a focal musical intervention, on the emotional memory of 4- and 5-year-old children. Each child individually looked at 24 neutral and emotional pictures and rated their valence and arousal. After that, the children were exposed to one of three interventions: musical improvisation (experimental intervention), musical reproduction (active control intervention), or rest (passive control intervention). Then, recall and recognition (immediate and deferred) were used to evaluate memory performance. The main results indicated that musical improvisation, compared with a reproduction music activity, improved memory. In addition, rest improved recognition compared with reproduction. Besides, children recalled more emotional than neutral images. Musical improvisation is a promising technique to be implemented in the educational field.

In music therapy, improvisation is a central practice; however, as a technique, it lacks methodological guidelines and scientific evidence justifying its use. The aim of this study was to investigate the social interaction features that emerge during group musical improvisation. We conducted a mixed methods study with an exploratory sequential design comparing improvisation and imitation tasks, performed by groups of younger and older adults, separately, by generating and analyzing six categories of nonverbal communication and social interaction. Method: Younger (n = 131) and older adults (n = 110) participated in one of two types of music activities: group musical improvisation or group rhythmic imitation. Eight group musical improvisation tasks-as implemented in music therapy settings-were compared with eight group rhythmic imitation tasks, according to six categories of analysis: visual contact, body movement, type of production, music interaction, vocal aspect, and leadership. Results: Statistical analysis using a Chi-square test (χ 2) showed greater social interaction among the participants of the improvisation groups than among those in the rhythmic imitation groups, in both age ranges. Conclusion: Our results provide specific evidence for this type of music task and a complementary approach to musical improvisation analysis, contributing to the knowledge of music therapy.

Understanding how and when acute stress improves or impairs memory is a challenge. Stressors can affect memory depending on a combination of factors. Typically, mild stressors and stress hormones might promote consolidation of memory processing and impair memory retrieval. However, studies have shown that during reconsolidation, stressors may either enhance or impair recalled memory. We propose that a function of reconsolidation is to induce changes in the behavioral expression of memory. Here, we adapted the Rey Auditory Verbal Learning Test (RAVLT) to evaluate the effect of cold pressor stress (CPS) during the reconsolidation of this declarative memory. A decay in memory performance attributable to forgetting was found at the time of memory reactivation 5 d after training (day 6). Contrary to our initial predictions, the administration of CPS after memory reactivation impaired long-term memory expression (day 7), an effect dependent on the presence of a mismatch during Reactivation Session. No differences in recognition tests were found. To assess putative sources of the negative memory modulation effects induced during reconsolidation, current emotional state was evaluated immediately after Testing Session (day 7). An increase in arousal was revealed only when CPS was administered concurrently with memory reactivation-labilization. The possibility of integration during reconsolidation of independent associations of these emotive components in the trace is a critical factor in modulating neutral memories during reconsolidation by stressors.

La música, como un potencial evocador de emociones, ha sido utilizada por la neurociencia como factor modulador de la memoria, ya sea potenciándola, o bien debilitándola. El presente estudio evaluó a una población de 71 adultos mayores sanos, divididos en dos grupos. Los mismos fueron evaluados a través de protocolos visuales y verbales, y expuestos a una pieza musical activante o ruido blanco. Los resultados indicaron que la música mejora la memoria emocional visual de adultos mayores sanos, pero no se logró comprobar lo mismo al evaluar memoria emocional verbal.

En el presente estudio, ratas macho adultas, que habian sido sometidas a estres neonatal cronico, se evaluaron en dos situaciones experimentales relacionadas con la frustracion: el Contraste Sucesivo Negativo consumatorio (CSNc) y la Extincion consumatoria (Ec). Los animales con estres neonatal, que tuvieron acceso a una solucion de sacarosa al 32%, y luego recibieron una devaluacion a una al 4%, presentaron una recuperacion mas rapida del efecto de CSNc (Experimento 1), y una Ec mas rapida cuando los animales recibieron una devaluacion de una solucion de sacarosa al 4% a un tubo de vacio, en comparacion con los animales no estresados durante el mismo periodo neonatal (Experimento 2). Estos hallazgos sugieren que las ratas adultas, expuestas de manera repetida a estres neonatal, ajustan ra...
